Donald, Yes, it is ridiculous that PTC's tutorial files will not open in the "Student" version. I have heard rumblings about this before, but I had assumed - incorrectly it appears - that PTC had straightened it out. I myself have not used the student edition, so I have not had personal experience with the tutorials. I don't know if there is any form of technical support open to you - I would try calling 800-477-6435 and get to an operator to see what your options are. Failing that, contact the reseller from whom you bought the software. And, yes, it is true that files are not compatible between commercial and student versions of Pro. This has been the case since at least the student version of ProE 2001, and possibly longer. Regards
